ABSTRACT

The present invention relates to an automatic viscosity control system and method for food products dispensed from frozen beverage and soft-serve ice cream equipment. A mixing cylinder includes an auger interconnected with an auger motor. A refrigeration system chills the food product in the mixing cylinder to a predetermined frozen malleable consistency. A motor sensor measures amperage draw or torque of the auger motor resultant from resistance of rotating the auger through the food product. By transitioning between starting or speeding up a compressor when the amperage draw or the torque of the auger motor is below a predetermined high motor performance setting, and slowing or stopping the compressor when the amperage draw or the torque of the auger motor is between a predetermined low motor performance setting and the predetermined high motor performance setting the viscosity of the food product is automatically controlled.

TECHNICAL FIELD OF THE INVENTION

This invention relates to an automatic viscosity control system for food products dispensed from frozen beverage and soft-serve ice cream equipment. This invention also relates to a portion control system to automatically dispense a predetermined amount of frozen beverage or soft-serve ice cream.

BACKGROUND OF THE INVENTION

Before our invention, a shortcoming of frozen beverage and soft-serve ice cream machines was that a service person had to manually set most of the control features such as temperature and spring tension for product freeze-up control. In this regard, if the product began to freeze solid a spring lever tripped a mechanical switch causing the refrigeration system to turn ‘OFF’ allowing the product to warm and thaw. As a result, product viscosity, consistency, and product quality vary widely even between consecutive dispenses. When dispensing a product sometimes the product is too frozen and difficult to dispense other times too warm and runny.

Another shortcoming is that even when a frozen beverage or soft-serve ice cream machine was manually set to deliver products not too frozen and not too runny something as simple as ambient temperature or humidity changes can cause the consistency of the product to change requiring more manual intervention adjusting the machine setting to improve product quality.

Another shortcoming of frozen beverage and soft-serve ice cream machines is that absent the ability to automatically control the viscosity of the product, quick-serve restaurants, and other establishments are unable to reliably and repeatedly automatically dispense exact product volumes such as small, medium, and larger size portions with consistent and acceptable accuracy.

The present invention addresses these and other shortcomings by providing automatic viscosity control and portion control systems and methods for frozen beverage and soft-serve ice cream machines. For these reasons and shortcomings as well as other reasons and shortcomings there is a long-felt need that gives rise to the present invention.

DETAILED DESCRIPTION OF THE INVENTION

Turning now to the drawings in greater detail, it will be seen that in FIG. 1 there are illustrated examples of frozen beverage equipment and soft-serve ice cream equipment. The frozen beverage equipment 102 and soft-serve ice cream equipment 104 are commonly found in restaurants, quick-serve restaurants, convenience stores, and numerous other locations.

In an exemplary embodiment, each frozen beverage equipment 102 and soft-serve ice cream equipment 104 can comprise one or more separate mixing cylinders 524 that contain a food product 302. The mixing cylinders 524 receive a food portion 306 from a food portion supply 562 and a gas portion 304 that form the food product 302. Selectively, in some exemplary embodiment, a water portion 308 can also be supplied. Each of the food portion 306, gas portion 304, and water portion 308 are ratiometrically injected into the mixing cylinder 524 so that the percentage proportion of each to the other is maintained. The food product 306 is chilled in the mixing cylinder 524 and dispensed through a dispense valve 526. Such food product 524 dispensing can be automated and portion-controlled or effectuated by a user 402 or customer 404 manually.

The term “ratiometrically” or “ratiometric”, in the present invention, is intended to mean two or more ingredients, portions, or other contents being mixed in a continuous predefined ratio regardless of the total volume being mixed forming a ratiometric mixture, such as of the food product 302. Such portions can be the food portion 306, the gas portion 304, water, or other portions. Each ingredient, portion, or other content is mixed in a predefined ratio with respect to each of the other ingredients, portions, or other contents, as may be required and/or desired in a particular embodiment. In this regard, any volume of the final mixture comprising the ingredients, portions, or other contents can be produced. Such gas portions can be air, carbon dioxide, nitrogen, or other gas portion.

The frozen beverage equipment 102 and soft-serve ice cream equipment 104 can be configured with any number of mixing cylinders comprising the same or different kinds of food portions 306, gas portions 304, and thus food products 302. Illustrated in FIG. 1 , as an example and not a limitation, frozen beverage equipment 102 is shown with two separate mixing cylinders 524 and dispense valves 526. Soft-serve ice cream equipment 104 is shown with two separate mixing cylinders 524 and dispense valves 526, and one additional dispense valve 560 that combines food products from both mixing cylinders 526 into a single dispense stream 558. This configuration is common where one mixing cylinder comprises, as an example, chocolate ice cream, the other mixing cylinder comprises, as an example, vanilla ice cream, and the additional dispense valve 560 dispenses 558 a mixture of chocolate and vanilla ice cream.

In operation, the food product 302 is injected into mixing cylinder 524 as a food portion 306, a gas portion 304, and selectively a water portion 308 and then chilled to a predetermined frozen malleable consistency. A user 402 or customer 404 can then dispense the food product 302 by way of a dispense valve 526. The gas portion 304 can be air, carbon dioxide, nitrogen, or other types and kinds of gases, as may be required and/or desired in a particular embodiment. In an exemplary embodiment, gases such as carbon dioxide, and other gasses can be injected into the mixing cylinder at a sufficient pressure to cause the gas to dissolve into the food portion 306 resulting in the food product 302 becoming carbonate in the case of dissolved carbon dioxide, or otherwise imbibed, or infused with the gas.

Referring to FIG. 2 , there is illustrated one example of temperature reference ‘A’, amperage or torque charts reference 13′, and a pressure chart reference ‘C’. An advantage, of the present invention, is that in an exemplary embodiment, automatic viscosity control of the food product 302 is achieved by enabling and disabling the refrigeration system 568 from chilling the food product 306 in the mixing cylinder 524 based on the electrical amperage current draw or the torque 214 of the auger motor 576, or both the temperature 204 of the food product 302 and the electrical amperage current draw or the torque 214 of the auger motor 576. In this regard, resultant from the refrigeration system 568, as the temperature 204 of the food product 302 decreases the food product 302 begins to chill into a predetermined frozen malleable consistency. This transition to a predetermined frozen malleable consistency increases the viscosity of the food product 302. The increased viscosity of the food product 306 in turn makes it more difficult for the motor 502 to rotate the auger 522 through the frozen malleable food product 302 increasing the amperage draw and the torque 214 of the auger motor 576. In an exemplary embodiment, by controlling the refrigeration system 568, ‘ON’ and ‘OFF’, based on at least the amperage draw or torque 214 of the auger motor 576 the viscosity of the food product 306 in the mixing cylinder 524 can be automatically maintained. For disclosure purposes, with reference to FIG. 2 reference ‘B”, the chart can represent either amperage draw 214 or the torque 214 and can be referred to as amperage draw or the torque 214

In an exemplary embodiment, in operation, an automatic viscosity control system for food products 302 dispensed from frozen beverage equipment 102 and soft-serve ice cream equipment 104 can comprise a mixing cylinder 524 comprising at least one of an auger 522, at least one of a product inlet 566 through which a food portion 306 is injected into the mixing cylinder 524, and at least one gas inlet 564 through which a gas portion 304 is injected into the mixing cylinder 524. A food product 302 comprises the food portion 306, and the gas portion 304. An auger motor 576 is interconnected with the auger 522. The auger is positioned inside the mixing cylinder 524 and turns stirring the food product 302.

A control system 500 comprises a microcontroller 502, a memory 504, and a motor sensor 530 (amperage draw) or 528 (torque). The motor sensor 528/530 is operationally related to the auger motor 576. The motor sensor 528/530 measures an amperage draw 528 or a torque 530 of the auger motor 576 resultant from the resistance of rotating the auger 522 through the food product 302. For disclosure purposes, the motor sensor can be one or both of the amperage meter 530 or torque monitor 528 referred to as motor sensor 528/530.

A refrigeration system 568 comprises a compressor 536. The refrigeration system 568 is configured to chill, to a predetermined frozen malleable consistency, the food product 302 inside the mixing cylinder 524.

The memory 504 can be encoded with instructions that when executed by the microcontroller 502 transition between the steps of starting or speeding up the compressor 536 when the amperage draw or the torque 214 of the auger motor 576 is below a predetermined high motor performance setting 218. And, slowing or stopping the compressor 536 when the amperage draw or the torque of the auger motor 576 is between 234 a predetermined low motor performance setting 216, and the predetermined high motor performance setting 218. In this regard, FIG. 2 , reference ‘B’, illustrates an amperage draw or the torque curve 214 electrical current amperages or torque in inch-pounds (or other units) versus time 210.

In another exemplary embodiment, the control system 500 can comprise a temperature sensor 542. The temperature sensor 542 is operationally related to the microcontroller 502 and the mixing cylinder 524. The temperature sensor 542 measures the temperature of the food product 302 inside the mixing cylinder 524. The memory 504 can be encoded with instructions that when executed by the microcontroller 502 perform the steps of starting or speeding up the compressor 536 when the temperature 204 of the food product 302 is above a predetermined high-temperature setting 206. And, slowing or stopping the compressor 536 when temperature 204 of the food product 302 is between a predetermined low-temperature setting 208 and the predetermined high-temperature setting 206 range 232, and the amperage draw or the torque of the auger motor 576 is between a predetermined low motor performance setting 216 and the predetermined high motor performance setting 218 range 234.

In this regard, FIG. 2 , reference ‘A’, illustrates a food product 302 chilling temperature curve 204 plotted as temperature 202 versus time 210. A predetermined food product 302 temperature range 232 is selected between 232 a predetermined low-temperature setting 208 and the predetermined high-temperature setting 206. Such food product 302 predetermined low-temperature setting 208 and the predetermined high-temperature setting 206 can be selected in the range 228 of where the food product 302 freezes plus or minus a few degrees.

Food product 302 viscosity plays an important role in the quality of the frozen beverage or soft-serve ice cream. If the food product 302 viscosity is too low it can make the food product 302 inconsistent, soft, and/or runny, and if the food product 302 viscosity is too high can make the food product 302 thick, or even frozen to the point that it can't easily be dispensed from the dispense valve 526.

In operation, several factors can influence food product 302 freezing and as such optimal food product 302 viscosity in a predetermined frozen malleable form. Such factors can include the amount of chill time at or near the food product 302 freezing point, the rotational speed of the auger 522, ambient conditions such as humidity, external temperature, and other ambient conditions, and the composition of the food product 302 such as the type, kind, and/or amount of sugar content, and other factors can influence the progression of freezing and the viscosity of the food product 302 as it freezes.

An advantage, in the present invention, is that in addition to closely monitoring and controlling the temperature of the food product 302, the viscosity of the food product is also closely monitored and controlled. In this regard, FIG. 2 , reference ‘B’, illustrates an auger motor 576 amperage draw or torque curve 214 plotted as electrical amperage or torque 212 versus time 210.

In operation, as the food product 302 chills and begins to freeze the viscosity of the food product 302 increases as it thickens, transitioning the food product 302 into a predetermined frozen malleable form. As the food product 302 thickens as it is chilled the viscosity increases applying more force to the auger 522 which in turn causes the auger motor 576 to draw more electrical current amperage and the torque 214 on the auger motor 576 increases too. For motor control systems that can determine torque, torque determination or measurements can be used along with or instead of using electrical amperage draw determination or measurements. One example of a motor control system that determines torque can be a variable frequency drive (VFD) that can be used as the auger motor 576. Other types and kinds of auger motors can also be used, as may be required and/or desired in a particular embodiment.

In another exemplary embodiment, torque can be measured mechanically by having a force of the food product 302 mixed in the mixing cylinder 524 applied to a lever that increasingly displaces as the food product 302 transitions to a predetermined frozen malleable consistency. The amount of displacement of the lever can be measured by the torque monitor 528 automatically electronically to determine a relative torque reading that can then be used in the methods of the present invention.

To achieve optimal food product 302 viscosity, a predetermined low motor performance setting 216 and a predetermined high motor performance setting 218 range 234 can be predetermined and set. The control system 500 can then disable the refrigeration system 568 when the amperage draw or torque 214 reaches the predetermined high motor performance setting 218 allowing the food product 302 to warm reducing the food product 302 viscosity. Similarly, if the amperage draw or torque 214 reaches the predetermined low motor performance setting 216 and the refrigeration system 568 is in the disabled state then the control system 500 can enable the refrigeration system 568 to chill the food product 302 which in turn increases the viscosity of the food product 302.

An advantage, in the present invention, is that operating together to automate viscosity control of the food product 302 can be controlled by controlling the temperature around the food product 302 freezing point 228 between a predetermined low-temperature setting 208 and a predetermined high-temperature setting 206 range 232, and the viscosity of the food product 302 between a predetermined low motor performance setting 216 and a predetermined high motor performance setting 218. The result is that the present invention delivers the food product 302 in an optimum frozen malleable form at a consistent viscosity automatically without a technician having to manually change equipment configurations.

In an exemplary embodiment, an alarm condition can be communicated by way of a display 506 or data communicated with a remote data processing resource 604 when a predetermined refrigeration chill period 230 elapses and the food product 302 has not sufficiently increased in viscosity to cause an increase in the amperage or torque 214 to reach the desired range 234. The control system 500 comprises the display 506 and the display 506 is operationally related to the microcontroller 502. In operation, the predetermined refrigeration chill period 230 is the amount of time allotted for the food product 302 to reach a predetermined frozen malleable consistency. Failure to achieve the desired predetermined frozen malleable consistency of the food product 302 in the allotted predetermined refrigeration chill period 230 can indicate equipment failures such as a refrigeration system 568 failure or other equipment failures.

In another exemplary embodiment, referring to FIG. 2 reference ‘C’ chart, pressure 222 within the mixing cylinder 524 can be determined over time 210. The pressure 222 is resultant from a gas portion 304 and a food portion 306 being initially injected in a predetermined ratio into the mixing cylinder 524. Food product 302 comprises the gas portion 304 and the food portion 306. The pressure 222 can also increase as the food product 302 transitions to a predetermined frozen malleable form.

In this regard, a product pump 552 is operationally related to the microcontroller 502 and interconnected between the product inlet 566 and the supply of the food portion 306 stored in package 562 such as a bag-in-the-box type or kind of packaging, or other types and kinds of packaging as may be required and/or desired in a particular embodiment. A gas metering device 548 is operationally related to the microcontroller 502 and interconnected with a gas inlet 564. The mixing cylinder 524 further comprises the gas inlet 564, and the product inlet 566. A pressure sensor 520 is operationally related to the microcontroller 502. The pressure sensor 520 is configured to measure a food product 302 pressure inside the mixing cylinder 524.

In operation, the memory 504 is encoded with instructions that when executed by the microcontroller 502 perform the step of filling the mixing cylinder, by way of the gas metering device and the product pump, with predetermined ratio of the gas portion to the food portion until the food product pressure is between a predetermined low-pressure setting and a predetermined high-pressure setting.

In another exemplary embodiment, a portion control system for food products 302 dispensed from frozen beverage equipment 102 and soft-serve ice cream equipment 104 can comprise a mixing cylinder 524 that comprises at least one auger 522, at least one product inlet 574, and at least one dispense valve 526. An auger motor can be interconnected with the auger 522. The auger 522 is positioned inside the mixing cylinder 524 and turns through and stirs the food product 302.

A control system comprises a microcontroller 502, a memory 504, a temperature sensor 542, and a motor sensor 528/530. The temperature sensor is operationally related to the mixing cylinder 524. The temperature sensor measures the temperature 204 of the food product 302 inside the mixing cylinder 524. The motor sensor 528/530 is operationally related to the auger motor 576. The motor sensor 528/530 measures an amperage draw or a torque 214 of the auger motor 576 resultant from the resistance of rotating the auger 522 through the food product 302.

The memory 504 is encoded with instructions that when executed by the microcontroller 502 perform the steps of injecting a food product 302 into the mixing cylinder 524 and chilling the food product 302 into a predetermined frozen malleable consistency. Receiving a portion-controlled dispense amount volume indicating the volume of the food product 302 to dispense. Determining a product temperature 204 of the food product by way of the temperature sensor 542. Determining the amperage draw or the torque 214 of the auger motor 522 by way of the motor sensor 528/530. Determining by querying a dispense time from the memory 504 or a remote data processing resource 604 based on the portion-controlled dispense amount volume. The product temperature 204, and the amperage draw or the torque 214. And, opening the dispense valve 526 for the dispense time, allowing the food product 302, in a predetermined frozen malleable consistency to be dispensed in a portion-control manner.

In an exemplary embodiment, the step of receiving referenced above the portion-controlled dispense amount volume can be effectuated by a data communication from a point-of-sale device, a quick-serve restaurant data processing device, a customer 404 or the user 402 initiated data communication from a digital communication device, a remote data communication from the remote data processing resource, manual data entry by the user at the portion control system, or by other methods or techniques as may be required and/or desired in a particular embodiment.

In an exemplary embodiment, the step of determining by querying reference above the dispense time is effectuated by a lookup table or a database encoded in the memory 504, the lookup table and the database correlates a plurality of the dispense time based on a plurality of the portion-controlled dispense amount volume, a plurality of the product temperature, a plurality of the amperage draw or the torque, and other factors, as may be required and/or desired in a particular embodiment.

In an exemplary embodiment, a product pump 552 is operationally related to the microcontroller 502 and interconnected between the product inlet 566 and the supply of the food portion 306. A gas metering device 548 is operationally related to the microcontroller 502 and interconnected with a gas inlet 564. The mixing cylinder 524 further comprises the gas inlet 564, and the product inlet 566. A pressure sensor 520 is operationally related to the microcontroller 502. The pressure sensor 520 is configured to measure a food product pressure inside the mixing cylinder 524. The memory 504 can be encoded with instructions that when executed by the microcontroller 502 perform the step of filling the mixing cylinder, by way of the gas metering device and the product pump, with a predetermined ratio of the gas portion to the food portion until the food product pressure is between a predetermined low-pressure setting and a predetermined high-pressure setting.

When the dispense valve 526 is first opened the food product pressure forces a surge of food product 302 also called overrun to dispense out of the dispense valve 526. When the food product pressure drops it is then the auger 522 that pushes the food product 302 out of the dispense valve 526.

In another exemplary embodiment, a pressure sensor 520 is operationally related to the microcontroller 502. The memory 504 is encoded with instructions that when executed by the microcontroller 502 perform the steps of determining, by way of the pressure sensor 520, a food product pressure 222 inside the mixing chamber 524. Determining, based on the food product pressure 222, a surge dispense amount of food product 302 also called overrun will initially be dispensed resultant from the food product pressure 222 when the dispense valve 526 is opened. And, adjusting the portion-controlled dispense amount volume desired, for purposes of determining the dispense time, by subtracting from the portion-controlled dispense amount volume the surge dispense amount.

In an exemplary embodiment, the food product pressure 222 is sufficient to force a surge dispense amount of food product 302 out the dispense valve 526 when opened. Once the food product pressure 222 drops resultant from the surge dispense amount egress through the dispense valve 526 it is the auger 522 that pushes the remaining desired food portion through the dispense valve 526. In a portion-controlled application, the surge dispense amount should be subtracted from the portion-controlled dispense amount volume before the dispense time is determined to better ensure food product 302 dispense accuracy.

As an example and not a limitation, at a predetermined temperature 204, amperage draw or torque 214, and food product pressure 222 the surge dispense amount is one ounce of food product 302, and the food product dispense flow rate is two ounces per second. Therefore if the desired portion-controlled dispense amount volume is nine ounces then the adjusted portion-controlled dispense amount volume is nine ounces minus the surge dispense amount or nine ounces minus one ounce which equals eight ounces. The dispense time then becomes the adjusted portion-controlled dispense amount volume divided by the food product dispense flow rate or eight ounces divide by two ounces per second which equals four seconds. The dispense time is then four seconds. In a plurality of embodiments, as temperature 204, amperage draw or torque 214, and food product pressure 222 change so will the surge dispense amount, and the food product dispense flow rate. In operation, an accessible lookup table or database in memory 504 or on a remote data processing resource 604 can correlate variables that change such as temperature 204, amperage draw of torque 214, food product pressure 222, the surge dispense amount, and the food product dispense flow rate, and other variables with the desired portion-controlled dispense amount to determine a dispense time to achieve an accurate portion-controlled food product 302 dispense.

In an exemplary embodiment, the auger motor 576 can be stopped and thus the auger 522 stopped during the surge period, this allows the surge amount to be predictably dispensed without the aid of the auger 522. Once the surge amount has been dispensed the auger 522 by way of the auger motor 576 can be restarted and it is then the action of the auger 522 that causes the food product 302 to be dispensed.

In an exemplary embodiment, during dispense of the food product 302, the auger motor 576 speed can be reduced proportionally as the temperature of the food product increases, the amperage draw decreases, or the torque decreases.

In a portion-controlled exemplary embodiment, a dispense lock 556 is operationally related to the microcontroller 502. The memory 504 is encoded with instructions that when executed by the microcontroller 502 transition between the steps of unlocking the dispense lock 556, allowing the food product 302 to be dispensed, when the temperature 204 of the food product 302 is between a predetermined low-temperature setting 208 and a predetermined high-temperature setting 206, and the amperage draw or the torque 214 of the auger motor 576 is between a predetermined low motor performance setting 216 and a predetermined high motor performance setting 218.

In the present invention “ideal consistency” is related to food product 302 viscosity and intended to mean the predetermined frozen malleable consistency of the food product 302 which can be easily dispensed from the dispense valve 526 yet frozen enough to be non-runny and user 402 and/or customer 404 desirable for consumption. In this regard, the predetermined frozen malleable consistency can be selected by the user configuring the frozen beverage equipment 102 and soft-serve ice cream equipment 104.

In operation, the memory 504 can be encoded with instructions that when executed by the microcontroller perform the steps of allowing the user doing equipment configuration to change the ratio of the food portion 306 with respect to the gas or air 304 portions. Then at least one of the predetermined low-temperature setting, the predetermined high-temperature setting, the predetermined low motor performance setting, or the predetermined high motor performance setting can be adjusted to maintain the predetermined frozen malleable consistency. In this manner, the ideal consistency of the food product 302 also called the predetermined frozen malleable consistency can be maintained even when the ratio of the food portion 306 with respect to the gas portion or air 304 changes. Noting that desirable mouth feel and other desirable customer consumption benefits of the frozen beverage or soft-serve ice cream can be obtained by changing the ratio of the food portion 306 with respect to the gas or air portion 304.

As an example, and not a limitation, a food product 302 with a food portion 306 and a gas or air portion 304 ratios of 60/40, 50/50, 40/60, or other ratios will all have different mouth feels and different customer consumption benefits at the predetermined frozen malleable consistency which can also be called the ideal consistency. To maintain the predetermined frozen malleable consistency across various food portion 304 and a gas portion 306 ratio changes at least one of the predetermined low-temperature setting, the predetermined high-temperature setting, the predetermined low motor performance setting, or the predetermined high motor performance setting can be adjusted. The present invention will then automatically maintain the desired predetermined frozen malleable consistency for the ratio of food portion 306 to gas or air portion 304.

An advantage, in the present invention, is that food product 302 ideal consistency can be achieved by maintaining the food product 302 between a temperature range defined by a predetermined low-temperature setting 208 and a predetermined high-temperature setting 206, and between a motor performance range defined by a predetermined low motor performance setting 216 and a predetermined high motor performance setting 218. Such food product 302 ideal consistency is automatically maintained by holding the food product 302 within the predetermined ranges of temperature 206/208 and motor performance 216/218 and such ranges can be adjusted manually or automatically in response to variances such as environmental conditions, equipment variances, food product 302 type or kind changes or variance, and other variances, as may be required and/or desired in a particular embodiment.

In an exemplary embodiment, in the present invention, by automatically maintaining the ideal consistency of the food product 302 even with variances in operating conditions the ability to determine a dispense time to dispense a desired portion-controlled dispense amount volume is effectuated. To increase the accuracy of the desired portion-controlled dispense amount volume a surge dispense amount must be taken into consideration. Since the ideal consistency can be relied on, the present invention uses food product pressure 222 to determine and control the surge dispense amount.

In this regard, the surge dispense amount the food product 302 occurs during the initial dispense when the dispense valve 526 is first opened. With the temperature range 206/208 and motor performance 216/218 established creating the desired food product 30 ideal consistency, the food product pressure 222 can be adjusted by establishing a food product 302 pressure range defined by a predetermined low-pressure setting 226 and a predetermined high-pressure setting 224. Once established the food product pressure 222 is maintained within the range resulting in a predictable and known surge dispense amount that can be used to adjust the dispense time so that the desired portion-controlled dispense amount volume is more accurately achieved.

In operation, while the food product 302 ideal consistency is maintained between the predetermined ranges of temperature 206/208 and motor performance 216/218 the surge dispense amount can be adjustably changed by changing the food product pressure range 224/226 and then repeatably maintained when the food product pressure 222, within the mixing chamber 524, is maintained between the predetermined low-pressure setting 226 and the predetermined high-pressure setting 224. Such food product pressure 222 is controlled by the amount of the food portion 306 and gas portion 304 that is injected into the mixing chamber 524. Changing the food product pressure 222 predictably changes the surge dispense amount.

In combination, the temperature range 206/208 and motor performance range 216/218 automatically control the viscosity of the food product 302 creating the ideal consistency while the pressure range 224/226 controls the amount of the surge dispense amount that is dispensed when the dispense valve 526 is first opened. Together, maintaining ranges in temperature 206/208, motor performance 216/218, and food product pressure range 224/226 effectuate the ability to dispense the food product 302 in a repeatably accurate portion-controlled manner.

Referring to FIG. 16 , there is illustrated one example of a portion control method for food products 302 dispensed from frozen beverage equipment 102 and soft-serve ice cream equipment 104. In an exemplary embodiment, a product pump 552 is operationally related to the microcontroller 502 and interconnected between the product inlet 566 and the supply of the food portion 306. A gas metering device 548 is operationally related to the microcontroller 502 and interconnected with a gas inlet 564. The mixing cylinder 524 further comprises the gas inlet 564, and the product inlet 566. A pressure sensor 520 is operationally related to the microcontroller 502.

In step 1202, decreasing the food product pressure 222 inside the mixing cylinder 524 to decrease a surge dispense amount of the food product 302 when the dispense valve 526 is initially opened. And, in step 1204, increasing the food product pressure 222 inside the mixing cylinder 524 to increase the surge dispense amount of the food product 302 when the dispense valve 526 is initially opened.

Referring to FIG. 17 , there is illustrated one example of a portion control method for food products 302 dispensed from frozen beverage equipment 102 and soft-serve ice cream equipment 104. In an exemplary embodiment, a pressure sensor 520 is operationally related to the microcontroller 502. The memory 504 is encoded with instructions that when executed by the microcontroller 502 perform steps 1206, 1208, and 1210.

In step 1206, a food product pressure 222 inside the mixing chamber 524 is determined, by way of the pressure sensor 520. In an exemplary embodiment, the ratio of the gas portion 304, food portion 306, and if necessary the water portion 308 influences the food product pressure 222 when it reaches the desired predetermined frozen malleable consistency. When the dispense valve 526 is first opened the food product pressure 222 forces a surge of food product to dispense out of the dispense valve 526. When the food product pressure 222 drops it is then the auger 522 that pushes the food product 302 out of the dispense valve 526. The method then moves to step 1208.

In step 1208, a surge dispense amount of food product that will initially be dispensed resultant from the food product pressure 222 when the dispense valve is opened is determined, based on the food product pressure 222. The method then moves to step 1210.

In step 1210, the portion-controlled dispense amount volume desired is adjusted, for purposes of determining the dispense time, by subtracting from the portion-controlled dispense amount volume the surge dispense amount.

In an exemplary embodiment, the food product pressure 222 is sufficient to force a surge dispense amount of food product 302 out the dispense valve 526 when opened. Once the food product pressure 222 drops resultant from the surge dispense amount egress through the dispense valve 526 it is the auger 522 that pushes the remaining desired food portion through the dispense valve 526. In a portion-controlled application, the surge dispense amount should be subtracted from the portion-controlled dispense amount volume before the dispense time is determined to better ensure food product 302 dispense accuracy.

As an example and not a limitation, at a predetermined temperature 204, amperage draw or torque 214, and food product pressure 222 the surge dispense amount is one ounce of food product 302, and the food product dispense flow rate is two ounces per second. Therefore if the desired portion-controlled dispense amount volume is nine ounces then the adjusted portion-controlled dispense amount volume is nine ounces minus the surge dispense amount or nine ounces minus one ounce which equals eight ounces. The dispense time can then be determined by the adjusted portion-controlled dispense amount volume divided by the food product dispense flow rate or eight ounces divide by two ounces per second which equals four seconds. The dispense time is then four seconds. In a plurality of embodiments, as temperature 204, amperage draw or torque 214, and food product pressure 222 change so will the surge dispense amount, and the food product dispense flow rate. In operation, an accessible lookup table or database in memory 504 or on a remote data processing resource 604 can correlate variables that change such as temperature 204, amperage draw of torque 214, food product pressure 222, the surge dispense amount, and the food product dispense flow rate, and other variables with the desired portion-controlled dispense amount to determine a dispense time to achieve an accurate portion-controlled food product 302 dispense.

Referring to FIG. 18 , there is illustrated one example of a portion control method for food products 302 dispensed from frozen beverage equipment 102 and soft-serve ice cream equipment 104. In an exemplary embodiment, the portion control system can be trained by encoding the memory 504 instructions that when executed by the microcontroller 502 performs the following step beginning in step 1302.

In step 1302, the food product 302 can be dispensed in a predetermined frozen malleable consistency form. The method then moves to step 1304.

In step 1304, the volume of food product dispensed is then determined. In this regard, since training is an iterative process, the amount of dispense can very to create an array of different data points. The method then moves to step 1306.

In step 1306, a training dispense time is determined in which the volume of food product was dispensed. In this regard, the dispense is timed so that a volume per second determination can be determined. The method then moves to step 1308.

In step 1308, the product temperature 204 of the food product is determined by way of the temperature sensor 542. The method then moves to step 1310.

In step 1310, the amperage draw or the torque 214 of the auger motor 576 can be determined by way of the motor sensor 528/530. The method then moves to step 1312.

In step 1312, storing in a lookup table or a database, in the memory 504 or accessible on the remote data processing resource 604, the training dispense time duration, the volume of food product dispensed, the product temperature 204, and the amperage or the torque 214 of the auger motor. In this regard, then during normal operational use, the lookup table or the database is updated and becomes queryable to determine the dispense time based on a desired portion-controlled dispense amount volume.

In an exemplary embodiment, the food product pressure 222 can also be correlated with other variables and stored in a lookup table or a database, in the memory 504 or accessible on the remote data processing resource 604.

Referring to FIG. 19 , there are illustrated exemplary embodiments utilized with the methods of the present invention.

In step 1314, the auger motor 576 can be stopped while the surge dispense amount is being dispensed. In this regard, stopping the auger motor 576 and thus the auger 522 during the surge period, allows the surge amount to be predictably dispensed without the aid of the auger 522. Once the surge amount has been dispensed the auger 522 by way of the auger motor 576 can be restarted and it is then the action of the auger 522 that causes the food product 302 to be dispensed.

In step 1316, the auger motor 576 can be slowed or stopped when temperature 204 of the food product 302 is above the predetermined high-temperature setting 206.

In step 1318, reducing, during dispense of the food product 302, the auger motor speed 502 proportionally as temperature 204 of the food product 302 increases, or amperage draw 214 decreases or the torque 214 decreases. In this regard, as the viscosity of the food product decreases (thins), the auger motor 576 speed decreases to maintain a constant flow rate of the food product 302 during dispense.

In step 1320, communicating an alarm condition by way of a display 506 or data communication with a remote data processing resource 604 when a predetermined refrigeration chill period 230 elapses. The control system 500 comprises the display 506 and the display 506 is operationally related to the microcontroller 502. In this regard, the predetermined refrigeration chill period 230 is the amount of time allotted for the food product 302 reaches a predetermined frozen malleable consistency after which a problem with the frozen beverage equipment 102 and soft-serve ice cream equipment 104 can be suspected.
